[vsnet-campaign-dn 577] CP Dra: superhump period revised

[Makoto Uemura <uemura@kusastro.kyoto-u.ac.jp>]

    Using new data sets kindly sent by D. Buczynski, 
the light curve obtained by the VSNET collaboration team 
(the Kyoto team, D. Buczynski, R. Novak, and J. Pietz) 
show 0.08348 (5) day periodicity.  This indicates the 
decreasing of the superhump period.  The object is gradually 
faded with 0.16mag/day from the maximum.  Our last night 
observation (March 6) were performed in hazy condition, 
but the average magnitude seems to show it entered a rapid 
decline phase.  Confirmations are encouraged.  
Tonight, it is cloudy in Kyoto.

Regards,
Makoto Uemura
